Hi all,I'm taking a 78 recording (and several others that I'm transferring) and trying to clean it up. I'm capturing the audio with Audacity at 32-bit IEEE float, as a stereo recording from a 78 stylus on my turntable at 45 then changing the speed, finishing it off with inverting the RIAA curve.My question is about cleaning up from this point forward understanding of course that one method simply won't work in every case.

I have Audacity, Sound Forge, DeNoise and ClickRepair. I've tried following this to a certain degree but I have no way of knowing if there's something I'm missing, if it's out of date, if there's a better way, etc. Mastering, I'm ok with. It's just the cleaning part I want to know with the aim of archiving these transfers.

Am I crazy to think that when I invert the RIAA curve the sound gets worse? The surface noise becomes far more prominent. I would imagine however that underneath that noise, the music itself is also having certain elements amplified and elevated but it's harder to tell under the amplified noise (A bit like trying to bring up the levels on a digital picture and battling with not blowing out the pixels to the point where you can see them?)In any event, all other editing of the sound will clearly have to be done by my own ear but it IS safe to assume that ANY 78 needs the RIAA curve inverted right?
